Topic: Railroad ATSI: Advanced Technology Safety Initiative
The nation's freight railroads have announced an initiative that will use innovative trackside testing technology to improve safety and efficiency on the rail network by giving freight car owners advance warning when freight car wheels are deteriorating.
The first effort under the new initiative is the use of data from wheel impact load detectors (WILD) to monitor the health of railcar wheels. When a freight car wheel exerts a peak impact load of 90 kips or above as measured by a WILD site, it is not operating effectively, is considered "out of round" and on the path to failure.
